Breathable film cover for window panes

Abstract

Breathable multilayer film covers for window panes that reflect light and/or absorb ultraviolet rays. The film cover blocks UV rays and some light, and it reflects solar heat. The breathable film cover has at least two film layers. An outer film is a polymeric transparent film incorporating UV stabilizers. An inner film is a polymeric film that contains internal metal particles and preferably UV stabilizers. An adhesive, preferably also incorporating UV stabilizers, is applied as a layer to the multilayer film so that the breathable film cover can be adhered to window structures. To form a covered window pane, the multilayer film is adhered to a plate.

1. A breathable film cover for window structures comprising:
 a first polymeric polyvinyl chloride film layer including internal metal particles and UV stabilizers; 
 a second polymeric polyvinyl chloride film layer secured to the first polymeric polyvinyl chloride film layer; wherein the second polymeric polyvinyl chloride film layer incorporates UV stabilizers and wherein the second polymeric polyvinyl chloride film layer is a clear stabilized film and 
 an adhesive layer applied to a surface of the first polymeric polyvinyl chloride film layer, 
 wherein the first polymeric polyvinyl chloride film layer, the second polymeric polyvinyl chloride film layer and the adhesive layer are permeable to moisture. 
 
     
     
       2. The film cover of  claim 1  wherein the adhesive layer incorporates UV stabilizers. 
     
     
       3. The film cover of  claim 1  wherein the adhesive has an ultraviolet light absorber. 
     
     
       4. The film cover of  claim 1  wherein the adhesive layer is an acrylic adhesive. 
     
     
       5. The film cover of  claim 1  wherein the adhesive layer is a clear pressure sensitive adhesive. 
     
     
       6. A breathable film cover for window structures comprising:
 a film including
 a first translucent polymeric polyvinyl chloride film layer including internal metal particles and UV stabilizers; 
 a second clear polymeric polyvinyl chloride film layer secured to the first translucent polymeric polyvinyl chloride film layer; the second clear polymeric polyvinyl chloride film layer incorporating UV stabilizers, and 
 
 an adhesive layer applied to a surface of the first translucent polymeric polyvinyl chloride film layer, the adhesive layer including UV stabilizers; 
 wherein the first translucent polymeric polyvinyl chloride film layer, the second clear polymeric polyvinyl chloride film layer and the adhesive layer are permeable to moisture. 
 
     
     
       7. The film cover of  claim 6  wherein the adhesive layer is an acrylic adhesive. 
     
     
       8. The film cover of  claim 6  wherein the adhesive layer is a clear pressure sensitive adhesive.
